ABSTRACT:
A mount for flexible connection of a vehicle propeller shaft to a vehicle body, including an inner sleeve and an outer sleeve, and an elastic body interposed between said inner and outer sleeves for elastic connection therebetween. The elastic body partially defines at least two pairs of upper and lower fluid chambers filled with a non-compressible fluid, between the inner and outer sleeves, such that the upper and lower fluid chambers of each pair are spaced from each other in a circumferential direction of the mount, and such that pressures of the fluid in the upper and lower fluid chambers change in opposite directions upon application of vibrations between the inner and outer sleeves. The upper and lower chambers of each pair are held in communication with each other through a suitable orifice.
